Build New Roof for Redwood Water Storage Tank

The tank itself was 10 feet tall, 14 feet in diameter and full of water within 2 inches of the top.

10 Foot Redwood TankRoof in terrible conditionThis roof was in terrible shape. The redwood tongue and groove sheeting was rotten in many places, the nails had let go and many boards were missing.

This makes for an interesting place to work. You wouldn’t want to fall in the water. And of course, any tools that are dropped would be gone forever!

Finally, the new T & G cedar was installed and an access hole cut and covered. Lastly, vents were added around the perimeter between the top of the tank and the bottom of the roof.
Actual cost for materials and labor:

  • Redwood 2x6x16
  • Cedar 1×6 T & G
  • Galvanized brackets
  • Screws, nails galvanized vents
  • Labor 14 hours

Actual Cost $2000
